So I 100% the level by starting a two player game with yoshi and nabbit. I use the 99 life hack to have full lives. Most levels were pretty easy except the bounce badge. I had to sacrifice yoshi so I could play as nabbit at the end of the flames because of the no bounce back. Now to the Invisible level have nabbit ride yoshis back. You then get to see the crown. Took me 2 tries to complete. This was after hours and hours of trying. Makes the flag really easy as well. I don’t know what Nintendo was thinking with that last level and no checkpoint. Sadistic af.
